有關has/have的用法問題？

是因為在問句的aux.v.=does已代表咗第三身單數,主動詞是不必轉用第三身has........用have就ok.

但答就要用第三身has........例=She has two books.

無錯，she 係跟has。
但要分開陳述句和問句是有分別的。


例如 she goes to work every morning.轉為問句 Does she go to work everymorning?


可能用翻個has做例句會更明白。

例如she has three cats.轉為問句Does she have three cats?
例如they have three cats.轉為問句Do they have three cats?

在句子Does she have three cats?中, 不能用has因為does己表示左單數。
就好似過去式咁 he went to school yesterday. 轉為過去式did he go to school yesterday?因為did己代表過去式，不用把go也轉成過去式went。


我諗你係一時醒唔起姐。

"How many books does she have?" is correct. When does is added, (usually in a question), then the basic form "have" should be used.

Other examples:

Did she have these books? (When did is used, then you use the basic form)

Did you know about that? I knew about that or I did not know about that.

Does she like the film? She likes the film or she does not like the film.

Hope that the above is helpful.
